速递|Instagram创始人炮轰AI聊天机器人:沉迷“数据泡沫”,偏离实用本质

他强调,行业应"聚焦于提供高质量答案",而非用"最低成本的方式刷数据"。 图片来源: Unsplash Instagram 联合创始人凯文·斯特罗姆( Kevin Systrom )近日公开批评当前 AI 聊天机器人行业陷 入"数据泡沫"陷阱——通过高频追问用户"诱导互动"以美化运营指标,而非专注于提供真正有价值的 答案。 在 StartupGrind 大会上,斯特罗姆直言这种策略是"一股伤害用户的势力",并将其类比社交媒体公司 早年激进扩张时期的策略:"你会看到某些 AI 公司正在掉进消费互联网公司曾深陷的'互动量黑洞'。 每当用户提问结束,系统总要追加一个诱导性问题,试图榨取更多对话次数。" 核心矛盾: AI 公司陷入"互动量陷阱"? 斯特罗姆指出,聊天机器人过度追求 "黏性"并非技术缺陷, 而是 AI 公司为炫耀"用户使用时长""日活量"等指标刻意设计的机制。 https://techcrunch.com/2025/05/02/ai-chatbots-are-juicing-engagement-instead-of-being-useful-instagram-co-founder-warns/ 编译 ...
